結(jié)合空氣凈化工程的概念及工作中積累的一些經(jīng)驗，現(xiàn)在從人、機、法、料、環(huán)五個方面來談談ESD的防護。

 

Combined with the concept of air purification project and some experience in the work, now from the people, machines, methods, materials, five aspects of the aspects of the protection of the ESD.

 

（一）人。人體可以說是一個高靜電源，人體靜電的防護，借助的是屏蔽及釋放靜電。嚴格來說要求做到“全副武裝”，即:要戴防靜電工帽、防靜電口罩、防靜電手套、指套等, 要穿防靜電服、防靜電鞋，同時還要戴上手腕帶等來屏蔽及導走靜電?？傊?，盡量不要讓人的皮膚外露。

 

(a) person. Human body can be said to be a Gao Jing power, the human body electrostatic protection, with the help of the shielding and release of static electricity. Strictly speaking requirements to achieve "heavily armed", namely: to wear anti static cap, anti static mask, anti-static gloves, fingerstall, to wear anti-static clothing, anti-static shoes, also will have to wear wrist belt to shield and guide the electrostatic. In short, try not to let people's skin exposed.

 

（二）機器。機器也是一個高靜電源，因為機器機械部件，特別是馬達等，易產(chǎn)生EMI（電磁感應），所以對機器靜電的防護，也是非常必要的。對于機器靜電的防護，一般通過電磁場的消除、高靜電部位的屏蔽、機器接地等來實現(xiàn)。一般消磁借用的是消磁器，消除電荷用的是離子風機。當電磁場無法消除或較難消除時，我們就借助靜電屏蔽設備來屏蔽高靜電設備或設備的高靜電部位，比如，馬達，大家都知道，馬達易產(chǎn)生EMI，但機器要運轉(zhuǎn)又離不開馬達，所以，不防把它屏蔽起來。還有工作臺、電源線、電腦鍵盤等，都可以接用靜電屏蔽的方法來做ESD防護，這方面可用的屏蔽產(chǎn)品有防靜電臺墊、防靜電薄膜、防靜電簾、防靜電屏蔽袋、防靜電膠帶等。最后，不管機器屏蔽或消磁效果如何，給機器接上ESD地線是很必要的。

 

(two) machine. The machine is also a Gao Jing power supply, because the mechanical parts, especially motors, etc., are easy to produce EMI (electromagnetic induction), so the protection of the machine's static electricity, but also very necessary. For the protection of the machine static electricity, the electromagnetic field is eliminated, the high static electricity parts of the shield, the machine to achieve. General degaussing is borrowed from the demagnetizer, eliminate the charge with the ion fan. When the electromagnetic field can not be eliminated or more difficult to eliminate, we have the use of electrostatic shielding equipment to shield high static electricity equipment or equipment, such as motors, we all know, Ma Dayi produced EMI, but the machine to operate and can not be separated from the motor, so it is not shielded. There are working table, power line, computer keyboard, etc., can be used to do ESD shielding method, which can be used to protect the shield products, anti-static pad, anti-static film, anti-static curtain, anti-static shielding bags, anti-static tape, etc.. Finally, no matter how the machine or machine to shield demagnetizing effect, connected the ESD wire is very necessary.

 

（三）料。即材料。如果產(chǎn)品對靜電很敏感，那么生產(chǎn)線上是不能有高靜電材料出現(xiàn)的，特別是離產(chǎn)品較近的區(qū)域，要盡可能用防靜電材料，比如元件盒、貨架、工作臺、運輸設備、清洗設備、化學試劑等，甚至連用的筆及筆記本都要用防靜電筆及筆記本，因為在您用筆時，它有可能會接觸產(chǎn)品。當然，如果產(chǎn)品對靜電敏感程度不是很高，可以酌情處理，但最好借助ESD實驗來證明一下，看看是否真的可以放心。

 

(three) data. Material. If product is sensitive to static electricity, so the production line is not high electrostatic materials, especially the region closer to the product, as far as possible with anti-static materials, such as component boxes, shelves, such as working platforms, transportation equipment, cleaning equipment, chemical reagent, even even with pens and notebooks to anti-static pens and a notebook, because when you write with the pen, it is possible to come in contact with the product. Of course, if the product is not very sensitive to static electricity, can be appropriate, but it is best to use ESD experiments to prove that you can see if you can rest assured.

 

（四）環(huán)。即工作區(qū)域的環(huán)境。一個良好的防靜電的工作環(huán)境對于生產(chǎn)來說是很重要的。

 

(four) ring. Working area environment. A good anti - static working environment is very important for production.

 

（五）法。談起方法，首先要明確以上四點，其實法就是建立合理的方法及規(guī)范以保證以上四點有效實現(xiàn)。另外，當產(chǎn)生ESD原因不能明確時要根據(jù)生產(chǎn)工藝，設計相應的ESD實驗，來仔細查找產(chǎn)生ESD問題的原因。最終要建立相應的ESD操作規(guī)程及紀律規(guī)范來規(guī)范生產(chǎn)。

 

(five) method. Talking about methods, we must first clear the above four points, in fact, the law is to establish a reasonable method and specification to ensure that more than four points. In addition, when the ESD reason can not be clearly defined according to the production process, design the corresponding ESD experiment, to look for the reasons for the problem of generating ESD. Finally to establish the corresponding ESD operating rules and discipline to regulate production.

 

當然，空氣凈化工程 http://www.jnjkjh.com/ 防護系統(tǒng)建立起來以后，對于工作人員來說，所要做的是經(jīng)常檢測這個系統(tǒng)，以不斷的發(fā)現(xiàn)有不完善的地方，并做相應的改善，以保證系統(tǒng)長期有效的維持其ESD的防作用。這樣，建立相應的ESD職能部門，并不斷的培養(yǎng)其專業(yè)技能，提高其ESD防護意識，也都是空氣凈化工程防護中不可缺少的一部分。

 

Of course, air purification engineering protection system after the establishment of the staff, the need to do is to regularly test the system, in order to continue to find imperfect place, and to make the corresponding improvement, in order to ensure that the system is effective for the long-term maintenance of its anti ESD effect. In this way, the establishment of the corresponding functional departments of the ESD, and continue to develop their professional skills, improve their ESD protection awareness, but also an indispensable part of air purification engineering.
